According to Nazi racial theorists such as Hans F. K. Günther and Walther Darré, the Germans, the main branch of the Indo-Germanic Nordic people, had undergone a process of denordification over the centuries.
Even before taking power in 1933, the NSDAP developed a theoretical corpus designed to halt this process and strengthen the Nordic element within the Germanic Volk.
As a prelude to the creation of a Greater Germanic Reich on the scale of the European continent,[5] renordification was seen by its theorists as a long-term policy, both cultural and racial.
[8] Children born of relationships between women from occupied countries and German soldiers also underwent these racial examinations, entrusted to the NSV.
A network of SS-run orphanages was set up in the occupied territories, serving as a screen for the selection of "racially valuable" children.
